TYPE-WRITING MACHINE.

Specification of Letters Patent.

Continuation of application Serial No. 226,935, filed January 5, 1903.This application filed June 30,1905. Serial No. 267,805-

To (ti/Z whom it may concern:

Be it known that I, JACOB FELBEL, a citizen of the United States, and aresident of the borough of Manhattan, city of New York, in the county ofNew York and State of New York, have invented certain new and usefulimprovements in Type-WVriting Machines, of which the following is aspecification.

My invention relates to type-writing machines, and more particularly totype-bar baskets or rests therefor.

The object of my invention is to provide a simple construction oftype-bar basket or rest which is capable of greatly reducing the reboundof the type-bars when they strike the basket in their movements back tonormal positions, and thereby avoiding the lia- -b1lity of adjacenttype-bars conflicting or colliding near the type-bar basket during therapid operation of the machine.

To the above and other ends, which will hereinafter appear, my inventionconsists in the features of construction and combinations andarrangements of parts hereinafter described, and particularly pointedout in the appended claims.

In the accompanying drawings, wherein like reference characters indicatecorresponding parts in the various views, Figure 1 is a verticalfront-to-rear sectional view of one form of type-writing machineembodying Fig. 2 is a vertical longitudinal sectional view of thebasket, the view being taken on the line at :c of Fig. 1 and looking inthe direction of the arrow in said figure. Fig. 3 is an enlarged detailfragmentary perspective view of the pad shown. in Figs. 1 and 2. Figs. 4and 6 are like views showing other forms of pads embodying my invention.Fig. 5 shows in perspective other forms of pins which may be employed.Fig. 7 is a plan view of a pad shown in Fig. 6, and Fig. 8 is anenlarged detail fragmentary perspective view of still another form ofpad wherein both felt and leather may be employed in the constructionthereof.

The frame 1 of the machine is surmounted by a top plate 2, whichsupports a suitable carriage (not shown) that is provided with a platen3, (Diagrammatically illustrated in Fig. 1.

The key-levers 1 are pivoted on a rod 5 and have the usual finger-keys 6and restoringsprings 7. Pivotally connected to the key lever at S is asublever 9, the lower portion of which is slotted at 9 for cooperationwith the fixed fulcrum-rod 10, that extends from side to side of themachine. To the upper end'of each sublever is pivoted at 1 1 a link 12,which is pivoted at its forward end 13 to a type-bar 14. To eachtype-bar is pivoted at 15 a link 16, to which one end of a spring 17is'connected, the other end of said spring being connected to a hook 18,secured to the type-bar basket, designated as a whole by 19. The varioustype-bars are pivoted on a segmental pivot-wire 20, that is carried bythe type-bar segment 21, and the type-bars are adapted to strikeupwardly and rearwardly.

The type-bar basket 19 1s rigidly supported by rods 22, that extendforwardly from' the type-bar segment. Said basket comprises a rigidsegmental metallic case or support 23, that is trough-like or U-shapedin cross-section, and this device supports a pad 24 throughout orsubstantially throughout the length thereof. This pad maybe made of onepiece of felt or other like soft or yielding material or of two piecesof different materials. Extending transversely of the pad and seated orembedded therein edgewise of the pad and at intervals throughout itslength are horizontally disposed parallel pins 25 which are preferablyof a non-resilient material, such as copper or lead. In Figs. 1, 2, and3 these pins are indicated as separate pieces and are entirelysurrounded by the pad, excepting at their ends. From an examination ofFig. 1 it will be observed that the sides of the trough-like supportextendvup and over the ends of the pins, so as to prevent a longitudinal displacement thereof from the pad.

The pins instead of being separate pieces, as indicated in Figs. 1, 2,and 3, may be connected or made in the form of staples 25*, as in Figs.4 and 8, or the pins may be connected one to another throughout theseries thereof, as indicated in Figs. 6 and 7, wherein a comb-like pieceof copper or other suitable hard or inflexible material is seated orembedded in the pad. The various pins, fingers, or projections 25 extendlaterally from a connecting-bar 25, so as to form a comb like structure.The pins may extend in substantially the same relation to the pad as theseparate pins 25 shown in Figs. 1, 2, and 3. The construction shown inFigs. 6 and 7 from certain aspects may be regarded as a the-impact ofthe type-bars.

- pad.

pad having a longitudinally-extending metallic strip seated or embeddedtherein, the

-metallic strip having openings or spaces at stitching b, with thetransverse pins or metallic pieces interposed between them.

In the employment of a pad such as just described I prefer to use thefelt strip to receive In any detail construction a felt pad or facingreduces noise to the minimum; but unfortunately it causesan excessiverebound of the type-bars unless some means are specially provided forreducing the same. This I have provided, and my pads yield the minimumof sound and rebound.

It willbe observed that the pins or pieces extend in the generaldirections of the type bar's when the latter are at rest on the padwhich normally supports the free ends thereof; that the pins or piecesare fixed within the pad; that certain of them have intermediateconnections; that the pins or pieces ex-; tend substantially under andcrosswise of the ,upper or contact face of the pad and substantiallyparallel to said face and that they are arranged transversely of the padthat the comb-like piece shown in Figs. 6 and 7 .extendsthroughout orsubstantially throughout the length of the pad and has a portion 4 that.extends longitudinally ofthe pad and integral projections, pins,'orfingers that project therefrom transversely of the pad; that the metalpins shown in Fig. 8 are interposed between a plurality of strips ofmaterial that extends longitudinally of the pad, and that in the variousconstructions shown the comb .or pins are embedded in the pad within thefield-of impact of the type-bars against the The pins or metallic piecesmay be inserted while the pad portions are straight, and

thereafter the pads may then be given a curvature corresponding to thesegmental support'23 provided therefor.

If'desired, each pad may be made of several segmental sections buttingend to end, though I prefer'to make each pad continuous, as shown.

Although I prefer to' make the rebound- ,i f ducing pins, fingers, orteeth of metal, nevertheless some other equivalent material may *beemployed instead in so far as the broader they have practically noresiliency and 0 erate to reduce the rebound of the typears to an extentsuch that there is no clashing of adjacent type-bars in the vicinity ofthe pad when the type-bars are operated rapidly. By using a felt or softmaterial for the face of the pad there is little or no sound resultingfrom the impact of the type-bars on their return movements to rest.Hence the desideratum is obtained of a practically noiseless'pad withthe rebound reduced to a minimum.

What I claim as new, and desire to secure by Letters Patent, is
